Why was he so cruel?

We connected a couple of years ago through work. Flirted for several months then when we finally hung out outside of work things intensified dramatically. It was literally like when you see in the movies where they can’t take their eyes off of each other. That’s where things flipped from fun and flirty to feeling/having emotions. Unfortunately, it caused drama and I left the job shortly after. He asked me not leave and told me he was sad that I was, but I was kind of forced out. (He was a doctor and married.)

A few months later we talked…I told him I was having a hard time moving on and that I felt something genuine and real with him. He said he felt similar but obviously it couldn’t go anywhere.

Fast forward a few years. He avoids me if we run into each other…which I didn’t think we ended badly, so it hurts. I finally asked him and told him that it hurt me. He basically ridiculed me. Told me it was just one night and how could I possibly feel anything. Kind of snickered through some of his responses. Told me it was nothing more than attraction and not to read anything into it…that it was just a fantasy and not reality. He also said, “I don’t hâte you. It’s not personal. We just can’t be friends though. I don’t have friends that my wife doesn’t know about or friends that are women.”

I don’t get it. I understand that it’s been a long time but never expected him to be harsh or to get such a completely different vibe. I expected him to say he had moved on but didn’t expect him to negate the whole experience.
